摘 要: 以北拒马河南支渠道倒虹吸防护工程为例,探讨采用垂直防护与柔性水平防护相结合的形式,以减小倒虹吸工程上下游采砂坑引起的上游顶冲冲刷和下游溯源冲刷。 The inverted siphon protection engineering in North Juma River south branch channel is taken as a example. The scouring erosion in upstream and retrogressive erosion in downstream is caused by the sand mining pits in upstream and downstream of inverted siphon projects, this paper expounds the combination of vertical protection with flexible horizontal protection to reduce the erosion.
